1o claims. (ci. 24S- 201) The present invention relates generally to theart of supporting plural hangings for windows, doorways, etc. includingshades, curtains, cornices, draperies, and like. The herein invention isprimarily 'directed to providing novel universal support brackets formounting various types and sizes of a plurality of brackets and fixturesutilized for the aforesaid purpose.

ln accordance with the present invention, I provide a novel set ofbracket supportsupon which any conventional type and construction ofbracket or mounting for the following items may be directly and readilysupported: rods, poles, shades, blinds, including Venetian blinds,rings, pleaters, as Well as extender plates, extender rods, cornices,angles, etc. The bracket supports of this invention are not limited toparticular sizes, shapes or constructions of the auxiliary brackets forthe various mountings. Generally, my universal support brackets arearranged in pairs, with the right and left brackets being symmetrical toeach other.V Where a rather large width is to be traverse'da thirdcentral universal bracket, corresponding for example to the rightsupport bracket, is used additionally with suitablefixtures to bedescribed. Further, fourth or fifth intermediate bracket supports may beused for centrally supporting unduly wide hangings.

in home and oce decoration of windows, doorways,

ctc. it has heretofore been requisite to nail or screw specie sets ofbrackets for the various hangings as used, and as changed through theseasons or for style. This resulted in excessive damage to plaster orwood trim about the windows or doors, weakening the mounting of suchspecial brackets, from season to season. Other than the weakening anddestruction of the mounting areas for'such specific bracket sets, it wasa tedious task to remove these 02d brackets and remount new bracketsdirectly upon lt is of course impossible to design or impractical tomake a single bracket construction which could be used for hanging orsupport of all the various hanging units as to size, shape and type.Accordingly, the prior art utilized specialized brackets often withspecific .adjustments for the various uses referred to, and to be setforth in more detail. l

lt is an importantrobje'ct of theY present invention to provideuniversal bracket supports which are readily mountable on the wall orframe about a window or doorway, which universal bracket supports orsupport brackets readily mount a plurality of sets of specific bracketsfor any requisite hanging array.` As hangings, rodsgpoles,l etc.generally are supplied with their requisite special brackets, my`universal supports are used directly with them. Such specialbracketsets are readily oriented in desired relationships on the inventionAuniversal bracket supports, and are readily removable and replaceable.The specilc bracket sets mounted on the` universal brackets hereof arethereupon readily mounted as groups onthe wall or frame, and` alsoreadily rdemoruntable, necessitating no furtheri securement to thelbuildingstru- 2,974,918 Patented Mar. 14, 1961 ture once the inventionuniversal support base is initially aliixed. v

V" {he universal support brackets of my invention have a mounting platethat is nailed or secured by screws to the wall or trame, and upon whichthe `universal support brackets per. se is readily attached ordemounted. vThe invention universal brackets have slots, openingsv andVother means for readily securing individual specialized brackets theretoin varied arrangements. A right-hand and left-hand Asupport bracket aregenerally mounted adjacent the top corners of the window, doorway, orarea to be decorated.

The universal support brackets of the invention have series'orcoordinated vertical slots and apertures to accommodate correspondingright-hand and left-hand specialized brackets for a variety of hangings.The invention supports have a coordinated aperture and slottedv array ontheir respective faces, as well as on their sides. Further, extensionarms are utilized with the invention universal brackets foraccommodating specialized mount-V ings that are wider than'the verticaldimension of the tace thereof. A third universal support bracket jismounted intermediate the right-hand and left-hand uni-y versal bracketsfor central support of hangings that arel` unduly wide or heavy Vandrequire central support. InV such event the three universal brackets,and` their slot. aperture array, are coordinated for the specializedpurposes as required in wide or heavy hangings, as will be detailedhereinafter in connection with Figs. 14, 15 and 16.'

The invention universal support brackets are relatively inexpensive forthe very advantageous and practical re sults which they attain. Togetherwith the usually supplied'specialV brackets, they constitute thecomplete hang?A ing arrangements. The universal brackets of the inven-Vtion are lrelatively small and light in weight, and are readily hiddenamongst Vthe hangings Without projecting Y provide novel universalbracket supports for selective` mounting of one or more sets hangings. l

Anotherobject of the present invention is to provide a pair of universalsupport brackets each having an array ofv coordinated slots andapertures for selective mounting of one or more pairs of specializedbrackets for hangings for a window or doorway.

Still another object of the present invention is to provide noveluniversal bracket supports for accommodating speof specialized bracketsfot` cialized hanging bracket pairs of wide diversityof size,

type and function.

A further object of the present invention is to provide a noveluniversal support bracket .having longitudinal slots and apertures onits face and sides for coordinated, support of a variety of specializedhanging brackets.

Still a further object of the present invention is to provide a noveluniversal bracket arrangement incorporating` coordinated slots andapertures in conjunction withan extension arm for accommodatingspecialized hanging brackets with mounting positions longer than theface of` the universal bracket. Y n v Still another object of thepresent invention is to pro'-l vide relatively small and inconspicuousuniversal support brackets that readily harmonize with thehangings andvrmounting areas. v Y Another object of the present invention is toYprovide universal support Ibrackets 'for mounting afplurality of setsof specific hanging bracketsthat are relativelylight" in weight,inexpensive to-'fabrieate and simple to-u'se;

The right-handbracket is illustrated in enlarged perspective, With a window shadebracket 45 secured along the vertical inside edge 26 slots o and p. Itis to be realized that the longitudinal slots such as o and ppermit'vertical alignment and positioning for the hanging bracketssecured thereto. It is to be understood, further, that in thecorresponding lett-hand bracket 21, the inside face thereofcorresponding to face 26 of bracket 20 has the complementary hangingbracket to 45 mounted at the same relative position along the ve1ticalslots, in order that the two window shade brackets hold the shadehorizontally.

The window shade bracket 45 is mounted through apertures thereof withbolts 46, 46 against end 26 of bracket 20 and through the slots o and p.A conventional hook-arm curtain rod bracket 47 is shown mounted alongchannels h, i, of the universal bracket 2i? by bolts 48, 48. The curtainrod bracket 47 has a lateral extension 49 in the usual manner,projecting from the body of the bracket 47. The vertical alignment ofthe bracket 47 is accomplished by orientation along thelongitudinalslots h, z'. A right-side curtain rod bracket 47 is shownmounted on the right-side universal support bracket 20; it beingunderstood that a corresponding left-side curtain rod bracket is mountedon the counterpart universal support bracket (21) for the horizontalhanging of the curtain rod therefor.

A further specialized bracket 50 is also shown mounted on the universalbracket 20 of Fig. 9. The specialized bracket 50V is a combination oftraverse bracket (extending as adjustable projecting arm 51, see Fig.1G), and a valance rod bracket 52. The composite bracket 50 is securedby three bolts 53, 53 respectively engaged with vertical slots a, b, andc. The protruding adjustable armor bracket 50 is' shown cut-oit at thedotted portion in Fig. 9 for the sake ofeclarity of presentation,

It Vis noted that the combination bracket50 ismounted adjustably in the vertical direction along the slots a, b and c.Also, the traverse rod bracket portion 54 thereof isadjustable outwardlyalong the rail portion 55, 55 of bracket arm 51, and locked by machinescrew 56 in the desired extendedfposition. The cup-like portion 57 atthe end of arm 54 is' for holding the end of the traverse rod, as willbe understood by those skilled in the art. A

The bracket assembly of Fig. 9 accordingly illustrates the adjustablemounting offour ditterent and correlated hanging means, namely thewindow shade bracket 45, the curtain rodbracket 47, and the combinationtraverse rod and valance rod bracketS. It is to be understood thatthe'complementary left-side brackets` to these are mountedin themirror-symmetrical universal bracket 21 atthe left-side of the windowframe, as per `Pig. l. It is also to be understood that differentYbrackets and positioning thereof may be coordinated on the universalsup- Y port brackets 20, 21 of the invention.

Figs; 11, l2 and 13 illustrate an auxiliary aspect of the inventionsupport "brackets,` The cross-sectional Fig. 11, vertically through theuniversal bracket 2G, shows slot 30 through which an, extension arm 69is mountable. Fig. l2 illustrates extension arm 60, having a wider head61 than body 62.

The horizontal slot 30 in support bracket 2b is adjacent the back'offace plate 22, and presents a mounting support for the arm 60. Theaperture 65 at the exterior of arm 60 is for the mounting of externalspecialized hanging brackets, as shown in Fig. 13. Alternatively theother slot position 29 of bracket support 2) may be used in place of endslot 30, in conjunction with corresponding vertical slots on face 22for. adjustable mounting of extension arm 60. Further, two extensionarms corresponding to 60 may be used together with the universal supportbracket 20 for supporting two wider based specialized brackets, in amanner of Fig. 13.

In Fig. 13 two hanging brackets are illustrated mounted upon theuniversal bracket support 20. A rod-support bracket 66, having aU-shaped member 67 in which the end of a rod is positioned, is arrangedalong the vertical slots o, p of inside face 26 in the manner of windowshade bracket 45 of Fig. 9. Other inside type of brackets may instead beused, such as for Venetian blinds, etc. The drapery or pole rod bracket70 has support feet 71, 72 which span to a wider extent than the basicheight of mounting face 22 of the universal bracket 20.

For the support of bracket 70 the extension arm 60 is inserted andmounted with the universal bracket 20, in the manner of Fig. 11. Theupper mounting leg 71 of pole bracket 70 is secured .through the topopening 65 of bracket 60 by bolt 73. The lower mounting leg 72 issecured to a suitable aperture or slot on face 22 of universal bracket20 by bolt 74. The extension arm 60 is secured within slot 29 or 30 ofthe universal bracket 20 by bolt 63. The large based pole-bracket 7dthusY has ample leverage, and is rigidly held in position for supportingeven a heavy pole 75, a hollow brass rod herein for carrying a drapery.The pole end 75 is placed in cup-shaped portion 76, and fastened thereinby knurled screw 77.

it is clear that an additional too-wide based hanging bracket,corresponding to pole bracket 70, may be mounted on a single universalbracket 20 by the use of a second extension arm corresponding to 60through the respective slots 29 (or 30) in the t'op offace 24 thereof.It is also apparent that a too-wide based bracket, as well as otherspecialized hanging brackets corresponding to those shown in Figr9, orotherwise known to those skilled in the art, may be compositivelymounted in plural 'fashion upon each of the companion universal supportYbracket 26a is identical to that of the right-hand universal bracket 20.However it may be the left-hand one, if desired. v

Mounted on central backet 20aV is a center-post bracket 8i). Fig. 15illustrates the center-post bracket *,StlsecuredY to universalrbracket20a through appropriate apertures or slots thereof bybolts 81, 81. Thepost bracket Si) comprises a plate 82 arranged against face 22a ofuniversal bracket 20a, and has a tubular extension 83 with a centralaperture S4 therethrough. Accordingly, the center post 83 projectsperpendicularly'from the plane of the universal brackets 20, 20a and 21,and therefor the wall thereof, and has an aperture S4 throughwhichextension members for center supporting are mounted.

yIn Fig.Y 15 a curtain rod center-support S6' is secured in thecenter-post bracket through aperture V84 thereof and screw 85. In Fig.16 a'traverse rod center support bracket 9i) is mounted directly on theface V22a of the.

central universal bracket 20a by bolts, 9,1.' The traverse rod centersupport 9,0 is adjustable in a plane perpendicular to that efface22aby"ar1V arm 92'slidable in a channel of bracket 90, and secured inthe adjusted position 7 by screw 93.' The channel 94 at the end ofbracket 90 is the traverse rod support. It is to be understood that thecenter nbracket .support 29a may be used for lseveral simultaneoushangings, as brackets 86 and 90 together.

Figs. 17 and 18 illustrate the securement of extender plates ontherespective universal brackets 20 and 2l. Extender plate 95 is bolted tothe right-hand universal support bracket 29 in Fig. 17 through suitabletop bolts 96, 96 and a face bolt 97. The extender plate 95 is of theusual construction, permitting the mounting of brack-V ets at itsextended end 95', remote with respect to the universal bracket 2u. Plate95 is mountable in several positions thereon. Fig. 18 shows a left-handvbracket 21 mounting anV extender plate 98 in the verticalextensionposition by bolts 99,100. Securement of the additional brackets to thetop portion 98 Yextends the electiveness of the xed support Abracket 21.

The universal support brackets of the present invention may be used invarious additional practical and advantageous ways. For examplecornices, Valances, and festoon boards may be aixed directly to theuniversal brackets 22 23 along their respective top portions 24., 25,see Fig. 1. Such items may thus be bolted to the brackets Z2, 23 throughsuitable openings 28 (Fig. 3),V and theV brackets thereupon atiixed ontheir respective mounting plates in the manner of Fig. 8. Similarly,draperyl rods or drapery cranes may be secured directly to the verticalfaces of the respective universal brackets 22, 23, through suitableslots and apertures thereof. Further,
